Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities
Description
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Authenticated remote attackers can execute arbitrary commands or cause DoS on multiple Cisco Small Business RV routers due to insufficient input validation.
Vulnerability
The vulnerabilities reside in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers. They are caused by insufficient validation of user-supplied fields within incoming HTTP packets. An attacker can trigger the issue by sending a crafted HTTP request to the management interface. All firmware versions are affected; Cisco has not released updates [1]. The remote management feature (disabled by default) makes the interface accessible from the WAN if enabled [1].
Exploitation
An attacker must possess valid Administrator credentials for the target device. With those credentials, the attacker sends a specially crafted HTTP request to the web-based management interface over a LAN connection (or over WAN if remote management is enabled) [1]. No user interaction is required beyond the initial authentication.
Impact
Successful exploitation allows an attacker to execute arbitrary commands on the affected device with root-level privileges, or to cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition [1]. The attacker gains full control over the router or disrupts its availability.
Mitigation
Cisco has not released software updates that address these vulnerabilities. No workarounds are available [1]. Administrators should restrict access to the management interface to trusted networks and keep remote management disabled unless absolutely necessary. These products may be approaching end-of-life; replacement with supported models is recommended.
